I would guess 4-3-3 flat. You use 3 strikers is this case so it is more aggressive than 4-4-2. I am not sure, but the best result I had was like 11-0 or 13-0, it stops at this score since I had the same result in 5-6 games against teams with less than 11 players or all players in wrong positions etc. Nonetheless 4-3-3 is a classic formation used in the past in real football games before it became as scientific as it is today. Hope it helped.
